Image processing method and device and computer storage medium

The invention discloses an image processing method and device. The method comprises: obtaining a building probability graph of a to-be-processed image, wherein the building probability graph comprisesprobability information that a plurality of pixel points in the to-be-processed image belong to a building area; sharpening the building probability graph to obtain a sharpened building probability graph; and obtaining building boundary information of the to-be-processed image based on the sharpened building probability graph. The invention further discloses a corresponding device. By sharpeningthe building probability graph, a building area and a non-building area can be better distinguished, so that the extracted building precision is improved. 本申请公开了一种图像处理方法及装置。该方法包括：获取待处理图像的建筑物概率图，其中，所述建筑物概率图包括所述待处理图像中多个像素点属于建筑物区域的概率信息；对所述建筑物概率图进行锐化处理，得到锐化处理后的建筑物概率图；基于所述锐化处理后的建筑物概率图，得到所述待处理图像的建筑物边界信息。还公开了相应的装置。通过对建筑物概率图进行锐化处理可更好的区分建筑物区域与非建筑物区域，从而提高提取到的建筑物精度。
